Sb 2 Se 3 has attracted great research interest very recently as a promising absorber material for thin film photovoltaics due to its suitable bandgap, high absorption coefficient, and non-toxic, low cost, and earth abundant nature. In this work, a significant efficiency improvement to 4.8% of superstrate cadmium sulfide (CdS)/Sb 2 Se 3 solar cells is obtained by the controlled addition of oxygen during thermal evaporation of Sb 2 Se 3 films. Systematic materials and device physics characterization reveal that oxygen addition during Sb 2 Se 3 film evaporation significantly improves the CdS/Sb 2 Se 3 heterojunction quality through effective passivation of interfacial defect states, resulting in a substantial enhancement in device circuit voltage and short circuit current density. The 4.8% device is the highest efficiency thus far reported for Sb 2 Se 3 thin film solar cells. Copyright © 2015 John Wiley & Sons, Ltd.

Antimony selenide (Sb 2 Se 3 ) has been considered as a prospective material for sodium-ion batteries (SIBs) because of its large theoretical capacity. Whereas, grievous volume expansion caused by the conversion-alloying reaction leads to fast capacity decay and inferior cycle stability. Herein, the confined Sb 2 Se 3 nanorods in nitrogen-doped carbon (Sb 2 Se 3 /NC) with interfacial chemical bond is designed to further enhance sodium storage properties of Sb 2 Se 3 . The robust enhancing effect of interfacial Sb O C bonds can significantly promote electron transfer, Na + ions diffusion kinetics and alloying reaction reversibility, combining the synergistic effect of the unique confinement structure of N -doped carbon shells can efficiently alleviate the volume change to ensure the structural integrity. Moreover, in-situ X-ray diffraction reveals intercalation/de-intercalation, conversion/reversed conversion reaction and alloying/de-alloying reaction mechanisms, and the kinetics analysis demonstrates the diffusion-controlled to contribute high capacity. As a result, Sb 2 Se 3 /NC anode delivers a high reversible capacity of 612.6 mAh/g at 0.1 A/g with a retentive specific capacity of 471.4 mAh/g after 1000 cycles, and long-cycle durability of over 2000 cycle with the reversible capacities of 371.1 and 297.3 mAh/g at 1 and 2 A/g are achieved, respectively, and an good rate capability. This distinctive interfacial chemical bonds and confinement effect design shows potential applications in the improved conversion/alloying-type materials for SIBs.

The integration of superhydrophobicity and photothermal conversion offers transformative potential for addressing ice accretion challenges in outdoor infrastructure. However, current technologies are constrained by fluorinated chemical dependencies, complex manufacturing workflows, and limited substrate adaptability. Herein, we present a fluorochemical-free, eco-friendly, scalable coating system through a one-step spray deposition of antimony selenide (Sb2Se3), stearic acid (STA), and poly(methyl methacrylate) (PMMA). The synergistic incorporation of Sb2Se3 and STA creates a micro/nano structure with enhanced surface roughness (Ra = 189.937 nm) and low surface energy, achieving exceptional liquid repellency (water contact angle: 165°, sliding angle: 3°). The optimized Sb2Se3/STA/PMMA (Sb2Se3–SP) composite demonstrates remarkable substrate versatility, adhering robustly to diverse surfaces (metals, glass, paper, and wood) without requiring pretreatment. Notably, the Sb2Se3–SP coating exhibits a 4.67-fold extension in delayed ice freezing time (280 s at −20 °C) compared to that of uncoated substrate (60 s at −20 °C). Furthermore, the intrinsic photothermal conversion capability of Sb2Se3 enables rapid surface heating, rising to 80.0 °C in 180 s under 1-sun illumination (0.14 W/cm2), facilitating autonomous ice melting without external energy supply. Besides, the Sb2Se3–SP coating exhibits outstanding mechanical durability and self-cleaning property. This scalable, eco-conscious fabrication approach bridges the gap between laboratory innovation and industrial deployment, offering a sustainable pathway for energy-efficient anti-icing solutions in aviation power systems and cold-region infrastructure.

Environmentally benign and potentially cost-effective Sb 2 Se 3 solar cells have drawn much attention by continuously achieving new efficiency records. This article reports a compatible strategy to enhance the efficiency of planar n–i–p Sb 2 Se 3 solar cells through Sb 2 Se 3 surface modification and an architecture with oriented 1D van der Waals material, trigonal selenium (t-Se). A seed layer assisted successive close spaced sublimation (CSS) is developed to fabricate highly crystalline Sb 2 Se 3 absorbers. It is found that the Sb 2 Se 3 absorber exhibits a Se-deficient surface and negative surface band bending. Reactive Se is innovatively introduced to compensate the surface Se deficiency and form an (101) oriented 1D t-Se interlayer. The p-type t-Se layer promotes a favored band alignment and band bending at the Sb 2 Se 3 /t-Se interface, and functionally works as a surface passivation and hole transport material, which significantly suppresses interface recombination and enhances carrier extraction efficiency. An efficiency of 7.45% is obtained in a planar Sb 2 Se 3 solar cell in superstrate n–i–p configuration, which is the highest efficiency for planar Sb 2 Se 3 solar cells prepared by CSS. The all-inorganic Sb 2 Se 3 solar cell with t-Se shows superb stability, retaining ≈98% of the initial efficiency after 40 days storage in open air without encapsulation.

Finding a cost-effective semiconductor with commercial performance for photoelectrochemical (PEC) water splitting remains challenging. Sb 2 Se 3 , as a low-cost semiconductor, has excellent photo/electric properties for PEC water splitting. Via adjusting the Sb/Se ratio in the precursor ink, the Sb 2 Se 3 with favorable crystallographic orientation can be effectively controlled. The ink with an atomic ratio of Sb/Se = 1:3 induces the growth of a compact Sb 2 Se 3 film with a preferred orientation, resulting in rapid charge transport and high photocurrent. After depositing TiO 2 and Pt in turn, the photocathode with a structure of FTO/Au/Sb 2 Se 3 /TiO 2 /Pt exhibits a photocurrent density of 11.3 mA cm −2 at 0 V RHE . An unassisted solar water splitting device integrating the Sb 2 Se 3 -based photocathode with an inorganic perovskite photovoltaic cell achieves a solar-to-hydrogen efficiency of 2.45%. The efficient Sb 2 Se 3 -based photocathode shows promising potential for solar fuel production.

Low operating voltage, high theoretical capacity conversion alloyed anodes ideal for potassium ion anodes. However, how to address the structural deformation and volume expansion of the changed alloyed materials throughout the reaction process is a crucial topic. A novel nitrogen-doped graphene-decorated FeSe x -Sb 2 Se 3 /C nanofibers (FeSbSe-NGCNFs) composite is synthesized by adding dicyandiamide (DCDA) during electrospinning. Benefiting from porous one-dimensional nanostructure, graphene-decoration and rich nitrogen doping, the best electrochemical performance is shown by FeSbSe-NGCNFs when used as an anode in PIBs. FeSbSe-NGCNFs provide a reversible discharge specific capacity of 279.9 mAh/g at 100 mA g −1 after 100 cycles with a capacity retention of 87.6 %, in addition to a high capacity of 169.9 mAh/g at a high current of 3000 mA g −1 . After 1000 cycles, the composite retained 115.8 mAh/g of capacity at 1000 mA g −1 . The main causes of these exceptional cycling multiplicity properties are the porous structure that produces more carbon defects and active sites, increasing the amount of storage capacity for K + and speeding up K + transport and electron transfer, as well as the graphene nanosheet structure that enhances electrical conductivity and increases its specific surface area. Therefore, PIBs might benefit from the developed FeSbSe-NGCNFs as anode material.

Back surface recombination could have some adverse effects on superstrate antimony selenide (Sb 2 Se 3 ) solar cells. Anode interface modification, such as inserting a buffer layer with appropriate energy-level matching, is necessary. Here, a novel interfacial material, pyrolytic ammonium metatungstate (PAMT), prepared by spray pyrolysis deposition, was introduced to modify the back contract of antimony selenide solar cells. Morpho-structural and thermal analysis showed that this material is different from crystalline molybdenum oxide powder. Monology characterization showed that PAMT preferentially fills the space of the Sb 2 Se 3 grain boundary. The J–V test showed that this layer improved the interfacial contract between the absorber and the back electrode. The PAMT layer showed suitable energy matching with Sb 2 Se 3 , providing an effective channel for hole carriers transport from the absorber to the anode, and largely reducing back contact surface recombination. As a result, the PAMT-modified Sb 2 Se 3 device exhibited a much higher photovoltaic performance, significantly improving the efficiency from 5.27% to 6.11%. Graphical Abstract

Low-dimensional polarization-sensitive photodetectors have captured ever-increasing attention due to their unique applications in navigation, optical switching, and communication. However, to date, the study of dimensionality-dependent polarization-sensitive photodetectors has not received much attention. Herein, a double-faced polarization-sensitive photodetector based on an individual high-quality Sb 2 Se 3 microbelt is proposed, where both the wide and narrow side facets serve as irradiation targets. Polarization-sensitive measurements reveal the anisotropy in the photocurrents recorded parallel and perpendicular to the long axis of the Sb 2 Se 3 microbelt. Strikingly, the single Sb 2 Se 3 microbelt photodetector reveals the obvious perpendicular reversal with a 90° angle on polarization sensitivity from the wide surface to the narrow surface. With decreasing inclination angle, the anisotropic ratio varies from 1.18 to 0.87 gradually. Interestingly, the photodetector can lose its polarization sensitivity at a particular inclination angle. Angle-resolved polarized Raman spectroscopy confirms the asymmetry and anisotropic character of the Sb 2 Se 3 microbelt. The polarization sensitivity of the Sb 2 Se 3 microbelt photodetectors originates from the optical anisotropy induced by the crystal structure anisotropy, rather than one-dimensional geometry morphological anisotropy. The use of an anisotropic Sb 2 Se 3 microbelt in double-faced polarization-sensitive photodetection may contribute to new functionality in innovative optoelectronic applications.

An undesirable p–n heterojunction interface of Sb 2 Se 3 absorber with Cd-free electron transport layer (ETL) is one of the key problems hindering the efficiency improvement of Sb 2 Se 3 solar cell. Herein, a promising SnO 2 /TiO 2 ETL coupled with SbCl 3 treatment is introduced to improve the performance of Sb 2 Se 3 solar cell. The mechanism of SbCl 3 treatment on the crystal orientation of Sb 2 Se 3 thin film and the p–n heterojunction interface of Sb 2 Se 3 solar cell is disclosed combined with different characterization methods. The carrier transport property for Sb 2 Se 3 thin film is enhanced, and the conduction band offset (CBO) of TiO 2 /Sb 2 Se 3 interface is reduced from 0.57 to 0.20 eV by forming Sb 2 O 3 interlayer at TiO 2 /Sb 2 Se 3 interface after SbCl 3 treatment, by which the interface recombination and the open circuit voltage deficit of the device can be effectively decreased, and the interface bonding at TiO 2 /Sb 2 Se 3 interface can be effectively improved. Ultimately, the Cd-free Sb 2 Se 3 solar cell with configuration of ITO/SnO 2 /TiO 2 /Sb 2 Se 3 /Au achieves an efficiency of 5.82%, which is the highest efficiency in vapor transport deposition (VTD)-processed Cd-free Sb 2 Se 3 solar cell at present. This work is expected to fill in the blank of VTD-processed Cd-free Sb 2 Se 3 solar cell and offers a valuable reference for future band alignment of Sb 2 Se 3 solar cell.

Sb 2 Se 3 has appeared as a highly prospective anode material for lithium-ion batteries (LIBs) owing to its abundant resources, a remarkable theoretical capacity of 670 mA h g −1 , and the presence of both alloy and conversion reaction mechanisms. Nevertheless, its drastic volume change during cycling caused rapid capacity decay. To address these issues, a common approach is to combine Sb 2 Se 3 with carbon materials. In this study, Sb 2 Se 3 encapsulated in multi-walled carbon nanotubes (MWCNTs) were fabricated through a one-step low-pressure vapor-phase reaction, forming the Sb 2 Se 3 @MWCNTs composite. The nanosize effect of Sb 2 Se 3 can alleviate its structural fracture during cycling. MWCNT network is advantageous for electron/ion transport. Subsequently, poly(3,4-ethylenedioxythiophene) (PEDOT), a conjugated polymer, was employed as an electron-enhancing buffer layer to further coat MWCNTs, creating the Sb 2 Se 3 @MWCNTs/PEDOT. More importantly, the PEDOT layer could create a robust solid electrolyte interface (SEI). By adjusting the ratio of Sb 2 Se 3 to MWCNTs, Sb 2 Se 3 @MWCNTs/PEDOT-7:3 composite exhibited a capacity of 648 mAh g −1 after 200 cycles at 0.5 A g −1 and a capacity of 495 mAh g −1 after 970 cycles at 2 A g −1 , demonstrating a highly promising class of high-performance LIB anode materials.

Layered Sb2Se3 consists of infinite chains of repeating Sb4Se6 units stacked along the c-axis via Sb–Se covalent bonds, whereas they are linked by van der Waals force along the a-axis and b-axis. It usually tends to grow along the [hk0] orientation with low surface energy. However, [001]-oriented growth, which efficiently enhances charge transport, is often considered unstable due to its high surface energy. Herein, we propose a growth method to fabricate Sb2Se3 thin films with the preferential [001]-orientation on various substrates (Mo, MoSe2, SLG, NiO, SiO2 and FTO). This crystal facet design of preferentially [001]-oriented Sb2Se3 exposes the majority of the nanoribbons vertically aligned to the substrate, and thus maximally improves the charge transport, which may find applications in diverse optoelectronic devices. We confirmed their performance in photoelectrochemical water reduction. The preferentially [001]-oriented Sb2Se3 photocathode exhibited an impressive photocurrent density of −20.5 mA cm−2 at 0 V vs. RHE and a maximum photocurrent density of −28 mA cm−2 at −0.2 V vs. RHE under 1 sun AM 1.5 G illumination. Thus, the successful use of this [001]-Sb2Se3 photocathode paves the way for the development of high-efficiency Sb2Se3-based devices for optoelectronic applications.

Enhancing the electrical properties of Sb 2 Se 3 thin films through elemental doping is a crucial strategy to improve its potential applications in photodetectors. In this study, thin films of Co-doped Sb 2 Se 3 were fabricated through electrochemical deposition. When the doping concentration reached x=0.05, Sb 2 Se 3 thin films were effectively fabricated exhibiting [ hk 1] orientation and a large average grain size. Consequently, the electrical characteristics of the films were improved. Following the incorporation of an Al 2 O 3 barrier layer and CdCl 2 treatment of CdS layer, the photodetector utilizing a thin film of Sb 2 Se 3 with x=0.05 demonstrates a significant response within the visible to near-infrared spectrum under 0 bias conditions. The optimal results were achieved at a wavelength of 635 nm, where the dark current (I dark ) was measured at 5.9 × 10 −7 mA, responsivity (R) at 92 mA/W, detectivity (D*) at 2.11 × 10 12 Jones, and the fitting ideal factor (θ) was determined to be 0.959. The selectivity within the visible wavelength range, coupled with the excellent values of D* and θ, position the device as having significant potential for various applications.
